Gary,
With POINT/LINE/POLYGON layer types, MapServer tries to open the DATA as
shapefiles by default, that's why you get that error message. Assuming
your GDAL/OGR is built with GRASS support, then you should use
"CONNECTIONTYPE OGR" in your layer definition, and specify the path to
the dataset in the CONNECTION parameter.
More info on CONNECTIONTYPE OGR is available at:

I am using GRASS GIS with gdal and ogr support:

Mapserver works with no problems with shapefiles
I tried to link to a GRASS layer using the following layer definition and it
returned this error:
msDrawMap(): Image handling error. Failed to draw layer named 'ex_area'.
msShapefileOpen(): Unable to access file.
(/var/www/grassdata/Keinsmerburg2/site_data/ex_area/1_polygon)
msShapefileOpen(): Unable to access file.
(/var/www/grassdata/Keinsmerburg2/site_data/ex_area/1_polygon)
File permissions are set to www-data and are set to create and delete.
Any ideas? I would be very grateful
Gary
